The quark delocalization and color screening model (QDCSM) has been described in detail in Refs. [1]}, [2]}, [3]}, [4]}. Here,we just present the Hamiltonian of the model.
\(H &=& \sum _{i=1}^6 \left(m_i+\frac{p_i^2}{2m_i}\right) -T_c+\sum _{i<j} \left[ V^{G}(r_{ij})+V^{\chi }(r_{ij})+V^{C}(r_{ij})\right],\nonumber \\V^{G}(r_{ij})&=& \frac{1}{4}\alpha _{s} {\mathbf {\lambda }}_i \cdot {\mathbf {\lambda }}_j\left[\frac{1}{r_{ij}}-\frac{\pi }{2}\left(\frac{1}{m_{i}^{2}}+\frac{1}{m_{j}^{2}}+\frac{4{\mathbf {\sigma }}_i\cdot {\mathbf {\sigma }}_j}{3m_{i}m_{j}}\right)\delta (r_{ij})-\frac{3}{4m_{i}m_{j}r^3_{ij}}S_{ij}\right],\nonumber \\V^{\chi }(r_{ij})&=& \frac{1}{3}\alpha _{ch}\frac{\Lambda ^2}{\Lambda ^2-m_{\chi }^2}m_\chi \left\lbrace  \left[Y(m_\chi r_{ij})- \frac{\Lambda ^3}{m_{\chi }^3}Y(\Lambda r_{ij})\right]{\mathbf {\sigma }}_i \cdot {\mathbf {\sigma }}_j \right.\nonumber \\&& \left. +\left[ H(m_\chi r_{ij})-\frac{\Lambda ^3}{m_\chi ^3}H(\Lambda r_{ij})\right] S_{ij} \right\rbrace  {\mathbf {F}}_i \cdot {\mathbf {F}}_j, ~~~\chi =\pi ,K,\eta \\V^{C}(r_{ij})&=& -a_c {\mathbf {\lambda }}_i \cdot {\mathbf {\lambda }}_j [f(r_{ij})+V_0], \nonumber \\f(r_{ij}) & = & \left\lbrace  \begin{array}{ll}r_{ij}^2 &\qquad \mbox{if }i,j\mbox{ occur in the same baryon orbit} \\\frac{1 - e^{-\mu _{ij} r_{ij}^2} }{\mu _{ij}} & \qquad \mbox{if }i,j\mbox{ occur in different baryon orbits} \\\end{array} \right.\nonumber \\S_{ij} & = & \frac{{\mathbf {(}\sigma }_i \cdot {\mathbf {r}}_{ij})({\mathbf {\sigma }}_j \cdot {\mathbf {r}}_{ij})}{r_{ij}^2}-\frac{1}{3}~{\mathbf {\sigma }}_i \cdot {\mathbf {\sigma }}_j. \nonumber \)
